Maybe some will be 3D exclusive, some online only, some Disney Plus exclusive, a few saved for the 2027 50th Anniversary 8k boxset… And we’ll never see some of them. AOTC and ROTS still have unreleased deleted scenes (scripted and filmed, and included in the comic and novelisation) 15 years later. We didn’t see that scene with Luke building his saber from ROTJ for what, 27 years or something? The Lucasfilm archives must house many unique artefacts. Perhaps we’ll see a few more when Lucas opens his museum.
